To @ZZ whom iv' may concern-.f

Be it known that I, HERMAN B. SEELY, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Fireproof Floorings, of

1which the followingy is a specification.

My invention relates to improvements in fire proof iioorings, its object beingto provide a cheap, light and effective ooring practically proof against tire, water and smoke and so simple as to require no skilled labor in its shown inoperative connection with the liooring. Fig. 2 is a vertical section of the iiooring and ceiling, the plane of section being parallel to the beams. Fig. 3 is a perspective view ,of one of the corrugated metal vsheets forming a part of the ioorng. Fig. 4 is an enlarged vertical section similar to Fig. 2, illustrating the connection of the meeting edges of two corrugated metal sheets and the relation of the flooring-stri ps and ceiling-hangers thereto. Fig. 5 is a View, partly in vertical section and partly in side elevation, showing the re'- lation of the ceiling-hangers to the beams; and Fig. 6 is an elevation ofthe ceiling-hanger, the view being in the direction indicated by the arrow in Fig. 5.

In the views, A, A are parallel metal beams of ordinary construction adapted to support a floor and ceiling and B, B are corrugated metal sheets of suitable'dimensions resting upon and transverse to the beams and having at their meeting edges vertical flanges, b, b, preferably covered and held in contact .by caps, C.

The iianges, b, b, and cap, C, of each joint are inclosed in and covered by a longitudinal groove, d, in the lower edge of a suitable flooring strip, D, the margins, d', d', of the members on either side the groove ybeing shaped as shown in Fig. 4 to conform substantially to the adjacent gutters in the corrugated sheets, the bearing lines of the flooring strips being serial No. 514,186. (No model.)

coincident with the bearing lines of the corrugatious upon the beams. Nails, E, E, passing transversely through the ooring strips,

D, the caps, C, and anges, b, b, bind all the and in this use have the special advantage ot' providing uninterrupted and practically contiguous air-ducts across the beams and the llooring thus constructed is light, stiff, cheap and easily appliedand is substantially proof against lire, water, or smoke. In order, however, to guard against any possibleleakage, I prefer to provide suitably inclined drainage troughs, T, transverse to the corrugations of the strips, and immediately under the lines of juncture of the ends of the sheets. The ends of the sheets are overlapped and riveted, as shown in Fig. l, and the eXtreme end of each gutterof the underlying edge is preterably bent downward as at b', b', Fig. 3, to formadripspout. Anywaterpassingthrough the iloor, F, and the packing Ymaterial beneath it must pass along the corrugated sheets and drop from the drip spouts, b', b', into the corresponding drainage troughs, T, T, beneath and thusbe carried to suitable points of escape.

The fiooring thus described may evidently be' used in combination with a ceiling suspended and constructed in any desired manner, butit is particularly adapted to the use of the simple and eiective ceiling hanger illustrated in the drawings, in which,'G, G are the two members of an angle iron having va plane upper end, a portion of the member,

G, beingleft in the plane of the member, G', to form -a hook or bracket, g, as clearly shown in Fig. 5. In use, the member, G, lies in con tact with the upper iiange, a, of the beam, the plane upper end of the hanger being between the flanges, b, b, of two contiguous corrugated sheets with the hook, g, resting upon the upper face of the iiange, a. A

bracket, g', punched from the member, G, lies beneath the lower flange, a', of the bcam and an opening, g2, is formed in the lower end of the member, G, of cach of the hangers, these openings being adapted to receive and support ceiling strips, H, to which a ceiling of any known construction may be attached. The hangers, G, G', are supported not only by the hooks, g, resting upon the beams but also by the nails, E,E, which pass through the upper ends of the hangers as well as through the flanges, b, b, of the corrugated sheets. The sheets, B, B, are preferably of such width as to space the ceiling hangers along each beam so as to bring the ceiling strips at suitable intervals for lathi ng, or for the attachment of standard widths of metal ceiling sheets.

I-Iaving now described and explained my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a flooring, the combination with suitable supporting beams and corrugated metal sheets resting upon the beams and having at their lateral meeting edges upwardly turned flanges, of suitable fastenings rigidly connecting the contiguous flanges of said sheets; substantially as shown and described.

2. In a flooring the combination with suitable supporting beams and corrugated metal sheets resting upon the beams and having at their lateral meeting edges upwardly turned integral ilanges, of suitable fastenin gs rigidly connecting the contiguous flanges of said stri-ps.

3. In a flooring the combination with suitable supporting beams, and corrugated metal sheets resting upon said beams and having at their lateral meeting edges upwardly turned flanges, of metal caps covering the contiguous flanges of the strips and suitable fastenings rigidly connecting said caps and flanges.

4. In a flooring, the combination with snitable supporting beams and corrugated metal sheets resting on said beams and having at their meeting edges upwardly turned ilanges, of longitudinally grooved wooden flooring strips covering the contiguous flanges of the strips and having their bearings in the adjacent gutters of the corrugated sheets.

5. In a flooring, the combination with suitable supporting beams and corrugated metal sheets resting upon the beams and having at their lateral edges upwardly turned flanges, of metal caps covering the contiguous flanges ot' the sheets, longitudinally grooved wooden flooring strips covering said caps and flanges and suitable fastenings rigidly connecting said flooring strips, caps and langes.

6. In a flooring, the combination with suitable supporting beams and corrugated metal sheets resting upon said beams, of transverse drainage troughs suspended beneath the meeting ends of said sheets and adapted to receive water dripping from the sheet.

7. In a looriug, the combination with suitable supporting beams and corrugated metal sheets resting upon the beams, of transverse drainage troughs suspended beneath the meeting lines of the ends of said sheets, the ends of the gutters, of the corrugated sheets being bent downward above the drainage troughs to form drip spouts; substantially as shown and described.

8. In a flooring, the combination with suitable supporting beamsand corrugated metal sheets resting upon the beams and having at their lateral edges upwardly turned ilanges, ot ceiling hangers having their upper ends between the contiguous flanges ofsaid sheets and suitable fastenings connecting said flanges and hangers.

9. In a ooring the combination with suit able supporting beams and metal sheets resting upon the beams and having at their lateral meeting edges upwardly turned ilanges, of suitable fastenings rigidly connecting the contiguous flanges of said sheets.

l0. In a flooring the combination with suitable supporting beams and metal sheets resting upon the beams and having at their lateral meeting edges upwardly turned integral flanges, of suitablefastenngs rigidly connecting the contiguous flanges of said sheets.

ll. In a ilooring the combination with suitable supporting beams and metal sheets resting upon said beams and having at their meeting edges upwardly turned flanges, of flooring strips rigidly fastened to the contiguous flanges of said sheets.
